Experimental Investigation on the Flow Characteristics of ER Fluids III (3nd Report, Flow-Pressure Drop Characteristics clearance between Two Parallel Plate)

ER유체의 유동특성에 관한 실험적 연구 III (평행평판 간극내의 유량-압려강하 특성)

Electro-rheological(ER) fluids are suspensions which show an abrupt increase in rheological properties under electric fields. The rheological response is very rapid and reversible when the electric field is imposed and/or removed. Therefore, there are many practical applications using the ER fluids. The purpose of the present study is to examine the flow characteristics of electro-rheological fluids. The field-dependent yield stress are obtained from experimental investigation on the Bingham property of the ER fluid. Then the steady relationshup between pressure drop and flow rate of the ERF was two fixed parallel-plates was measured under application of an electric fields. The electrical and rheological properties of zeolite based electro-rheological fluids were reported.
